The embodiment of my invention shown herein comprises a refrigeratorcabinet 11 having compartments 12 and 13 provided with openings 14 and15 affording access thereto, doors 164 and 17 for closing said openings,and sealing means for sealing the joints between the walls of theopenings 14 and 15 and the doors 16 and 17.

The sealing means comprises a strip of spring metal 18 having one edge2O attached to the wall of the cabinet 11 about each of the openings 14and l5 by nails 21, or similar means, and having its free edge 22 bentinwardly, downwardly, and reversely upon itself to form a substantiallyfiat surface carrying a groove 23 having rounded edges 24 and 25. Theedge of each of the doors 16 and 17 is fashioned with a groove 26 and abead 27 which cooperate with the rounded edge 24 and the groove 23 ofthe spring metal strip 18 to form resilient sealing means between thewalls of the openings 14 and 15 and the cabinet doors 16 and 17.

From the above disclosure it will be obvious to those skilled in the artthat I have provided new and improved sealing means for the jointsbetween the cabinet and the doors affording access to its compartmentsfor sealing against the passage of'air.

The combination with a cabinet proi vided with a door opening, and adoor for closing the opening in said cabinet; of means for sealing thejoint between the walls adjacent the fopening in said cabinet and saiddoor, said means comprising a sin le strip of resilient metal having oneedge anged for attachment to the edge of the walls adjacent the openingand a free resilient body portion formin a groove, the free edge of saidbody portion and the portion joining the flange and the groove being sobowed as to form leaf springs, .and a non-metallic bead formed on saiddoors -to contact with the entire surface of the groove in said strip.

3. The combination with a cabinet provided with a door opening and anotch extending therefrom, and a door for closing the opening in saidcabinet; of means for sealing the joint between the walls adjacent theopening in said cabinet and said door, said means comprising a strip ofresilient metal having ay flange for attachment to the ed e of the wallswithin the opening and a bo y portion 'disposed in the notch ad'acentthe opening in said cabinet, said bo y portion having formed therein' agroove and two bowed portions adapted to serve as leaf springs, and abead on said doors to contact with the body portion of said strip.

The combination with a cabinet `protion and provided on the free edgewith a bowed portion adapted to serve as leaf springs, the two bowedportions retaining the body portieri substantially parallel to one sideof the notch about the opening, and a bead integral with the woodenfacing of said door, said bead being so formed as to contact with theentire surface of said body portion.

ln testimony whereof I hereunto aHiXed 20 n1 y si gndture.
